[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] See also Figures 1 to 5The utility model provides a fire smoke detector that is easy to install, including a smoke detector body 1 and a mounting frame 2. The outer side of the top of the mounting frame 2 is provided with a ring-shaped fixing plate 4, and the fixing plate 4 is provided with bolt holes 5 for installation. The top of the fixing plate 4 is close to the top of the house, and the bolts are driven into the top of the house through the bolt holes 5 to position the fixing plate 4. An opening is provided at the center of the bottom of the mounting frame 2. The top of the smoke detector body 1 is connected to the bottom of the fixing frame 3. The upper end of the fixing frame 3 extends into the mounting frame 2 from the opening at the center of the bottom of the mounting frame 2. The fixing frame 3 and the mounting frame 2 are connected by at least three groups of mounting components 6. In this embodiment, the mounting components 6 are preferably four groups, and each group of the mounting components 6 includes two Sliding rod 602, the two sliding rods 602 are arranged horizontally, and one end of the two sliding rods 602 passes through the same first limiting plate 606 and is connected to the first baffle plate 605 respectively, the other end of the two sliding rods 602 is connected to the inner wall of the mounting frame 2, a spring 603 is sleeved on the sliding rod 602, and one end of the spring 603 is connected to the side wall of the mounting frame 2, and the other end is connected to the first limiting plate 606, the first limiting plate 606 is provided with a limiting block 604 at the center of one side close to the first baffle plate 605, the limiting block 604 extends into the fixing frame 3 from the small hole on the side wall of the fixing frame 3, the first limiting plate 606 is rotatably connected to one end of the moving rod 601 at the center of one side close to the spring 603, and the other end of the moving rod 601 passes through the side wall of the mounting frame 2. During the installation of the smoke detector body 1, the limit block 604 of the installation component 6 passes through the small hole on the side wall of the fixing frame 3 and extends into the fixing frame 3 to achieve the installation and fixation of the smoke detector body 1. After the smoke detector body 1 is installed, the spring 603 is always in a compressed state, pressing the first limit plate 606 toward one side of the fixing frame 3, so that the first limit plate 606 can extend into the fixing frame 3 from the small hole on the side wall of the fixing frame 3.

[0027] In order to better implement this utility model, refer to Figure 2 and Figure 3In one embodiment, the moving rod 601 is located at one end on the outer side of the mounting frame 2 and is connected to the second limiting plate 7. The outer wall of the mounting frame 2 is provided with at least three groups of limiting components 8. In this embodiment, four groups of limiting components 8 are preferably provided. The number of limiting components 8 is consistent with the number of mounting components 6, and each group of limiting components 8 and each group of mounting components 6 are respectively located on the inner and outer sides of the mounting frame 2 in a one-to-one correspondence. Each group of limiting components 8 includes two support rods 801, one end of the support rods 801 is connected to the outer wall of the mounting frame 2, and the other end is connected to the second baffle 802. The two second baffles 802 in each group of limiting components 8 are both horizontally arranged, and the moving rod 601 is located between the two support rods 801 in a group of limiting components 8. When installing the smoke detector body 1, the limit block 604 will block the fixing frame 3 from entering the mounting frame 2. At this time, it is necessary to pull the moving rod 601 of each group of mounting components 6 outward so that the second limit plate 7 connected to the moving rod 601 exceeds the second baffle 802. During this process, the second limit plate 7 is horizontal. Then, the moving rod 601 is rotated to rotate the horizontal second limit plate 7 to the vertical direction, and the second limit plate 7 is released. Since the two second baffles 802 block the second limit plate 7, even if the spring 603 has an elastic force on the first limit plate 606 in the direction of the fixing frame 3, it cannot drive the first limit plate 606 to move. In this state, the first limit plate 606 will drive the limit block 604 to move in the direction of the limit assembly 8, so that the fixing frame 3 can smoothly enter the mounting frame 2. When the fixing frame 3 enters the interior of the mounting frame 2, the moving rod 601 is rotated to make the second limit plate 7 rotate to the horizontal. At this time, the spring 603 can drive the first limit plate 606 back to close to the first baffle 605, and drive the limit block 604 to extend into the small hole on the side wall of the fixing frame 3 to limit and fix the fixing frame 3.

[0028] In order to better implement this utility model, refer to Figure 4 and Figure 5 In one embodiment, a plurality of limiting bars 301 are vertically provided on the outer wall of the fixing frame 3, and a plurality of limiting grooves 201 are vertically provided on the inner wall of the bottom opening of the mounting frame 2 close to the fixing frame 3. The number of the limiting grooves 201 is the same as the number of the limiting bars 301, and they are aligned one by one. In this embodiment, there are three limiting bars 301 and three limiting grooves 201. In order to allow the limiting block 604 to accurately extend into the small hole on the side wall of the fixing frame 33 when the fixing frame 3 is inserted into the mounting frame 2 for installation, before the fixing frame 3 is inserted into the mounting frame 2, the limiting bars on the fixing frame 3 need to be aligned with the limiting grooves on the mounting frame 2, and then the fixing frame 3 is moved upward into the mounting frame 2.

[0029] In order to better implement this utility model, refer to Figure 2 and Figure 3In one embodiment, the length of the second limiting plate 7 is greater than the width between the two second baffles 802 , and the width of the second limiting plate 7 is less than the width between the two second baffles 802 .

[0030] In order to better implement this utility model, refer to Figure 1 In one embodiment, an opening is provided at the upper end of the fixing frame 3 , and the opening is used for connecting the circuit of the smoke detector body 1 .

[0031] Based on the above-mentioned fire smoke detector which is easy to install, its working principle is as follows:

[0032] First, fix the mounting frame 2 on the roof by inserting the bolts into the bolt holes 5, pull the moving rod 601 outward, and rotate the moving rod 601 so that the second limit plate 7 is vertical and blocked by the two second baffles 802, so that the moving rod 601 drives the first limit plate 606 and the limit block 604 to move toward the side of the limit assembly 8 to prevent the limit block 604 from blocking the installation of the fixing frame 3. After aligning the limit groove 201 and the limit bar 301, move the fixing frame 3 upward so that the fixing frame 3 enters the inside of the mounting frame 2, and then rotate the moving rod 601 so that the second limit plate 7 becomes horizontal. The first limit plate 606 moves toward the side of the fixing frame 3 under the elastic force of the spring 603, and drives the limit block 604 to be inserted into the small hole on the side wall of the fixing frame 3, so as to install the fixing frame 3.

[0033] In the description of the present invention, "plurality" means two or more than two, unless otherwise clearly and specifically defined.
